The members of a crew on a submarine were about to take battle stations, and the ship’s Captain was worried about a young seaman whose job it was to close the watertight doors between certain compartments. The young man didn’t seem to realize the purpose of his job, so the Captain undertook to impress him. He told him that if he failed his job, the ship would be lost. Not only that, some of the men aboard were specialists and it cost thousands to train each of them; they might be drowned. The Captain stated: “So you see how important it is that you do your job . . . this is a very expensive ship, and these men are very valuable.” The young crewman replied: “Yes sir, and then there’s me too.” The Captain stopped worrying.9
